To want to continue to avoid ex

[Updownup4me]

2.5 years after a breakup, we were together for over 5 years. A new friend since breakup - we work together - has asked me to join an activity club with her as we share a common hobby. She didn't know this, but my ex is also in this club and I still want to avoid him after the horrible way he treated me - I've moved on in my life but don't want to be his 'friend'.

AIBU to ask her to join a different, albeit smaller club with me instead? I'm afraid she'll think I'm being silly?

YANBU, dont join the club, and yes , explain to your friend and ask her. It would be good to let her know she's free to continue to join club A if she likes, but you won't be. I think most people would be sympathetic!

Yes, I'll suggest she goes ahead herself if she'd like to. I sometimes wonder if I should have forgiven and forgotten at this stage, but I don't dwell, just don't want any unnecessary interactions with him
